Windows 11 has been making the rounds in the Windows Insider program in various different versions, but now testers have access to what will almost definitely be the launch build that arrives to the general public on October 5. So if you want to get a jump on upgrading, there is a path available (more on that in a moment).
This specific release is build 22000.194. It previously went out to testers in the Beta channel, and Microsoft apparently feels it is now ready for prime time, hence its promotion to the Release Preview channel.
“In the Release Preview channel, you’ll get the upcoming version of Windows before it’s released to the world, with advanced quality updates and certain key features. These builds are also supported by Microsoft if you’re in the Windows Insider Program for Business,” Microsoft explains.
